A method of providing information relating to a telephone call, in a GSM cellular radio telephone network, to a data storage system (10). The method comprises receiving caller identity information at a Mobile Switching Centre (1) of the network during a call set up procedure between a mobile station (4) and the MSC (I) and storing the information at least temporarily at the MSC (I). An incoming call alert message is sent by the MSC (1) to a called device (5). In the event that the called device (5) answers or otherwise accepts the incoming call alert, a call answer message is sent to the MSC (1). In response to receipt of the call answer message, at least the received and stored caller identity information is output from the MSC (1) to the data storage system (10).
